Be 1t known that I, ERNEST-I1. Tnrorna citizen-of the United States," residingat New J Britain, county of Hartford, State of Con- 'necticut have invented ac'ertain new and useful Improvement in Locks, OfllVlllClllhQ followlng 1s a full, cjlear and exact descrlp tion.

' stantially on the line 4-4 ofFig. 1;

- a My invention r'elates tojlocks andIhas for its object to provide a lockwhich is'capabl'e,

of functioning the same as any one of a nunr ber of'different types of locksas heretofore constructed, thus requir ng -the' manufacturer to inake, or dealer to carryfinstockf locks of-but a single type instead of anumber of different types: It further has forits object to secure-this advantage in a lock which is adapted for use-on either right or 7 crank 32 extends between the slotted lug left hand doors. r 7 v The several. features of; the invention,- whereby the above mentioned and other;0b-' j ects may be attained, will be clearly understood from the following description and accompanying drawings, in which, a 1

Fig. 1 is'a side view' of my improved lp'ck with'a portion ofthe cover of the casing broken away; 1 '1 v 1, *Fig. 2 is a'sectional view taken-substantiaL' 1y on the line 22 of Fig. 1 and showing i one of the knobs of the lock by-"broken lines; I a Fig-3 isa sectional view,- partly 1I1QlGV21- tion, taken on line 33 of Fig. 1-; g C

Fig. 4 is a detail sectional View taken sub- Figs. 5 and'6 are views similar toFig-J 4, but on an enlarged scale and showing di-fferent arrangements of certain parts of the lock; A

. Fig. 7 is a side View of the parts shown in Fig. .6, but with the cover of: the casing. and with one of the shanks of the knobs of the lock removed; f j K- Fig. 8 is a detail view in perspective of one of the latch bolt operating hubs, forming a-component part of the lock; and l o Fig. 9 is a detail View in perspective of a stop member forming a component part of the look;

The lock illustrated in the drawings is provided with a case 2having a cover 4 secured thereon by screws 6, and a face-plate 8 secured on. the front edge thereof- The lock is further providedv with allock bolt 10 and a pintumbler lock12 having back l4'which is adapted to be actuated to. project The cylinder or catsand retract the bolt. ing ofth e pin'tumbler lockis screw-threaded through/an aperture 16; in on'e.;-side of the;

casing, there being an aperture in both sides of the casingso. as topermit the pintumbler i f lock to} be applied to either-sidethereof.) The lock is further provided; with ;a-,latch a the bolt and a washer 26 that bearsagainst, a lug 28 integral with the lock- C856,.S5Ll6l" lug having a groove or slotthlrough which;

said bolt stem extends. A rectangular abutment plate. 30 is secured on the rear-end of the latch bolt stennand one' arm ,of a bell- 28 and the abutment plate 30. .The other arm of the bell-crank82 is arranged-to be engaged by a block or bar .34 mounted toslide transversely onthelock bolt 10, and adapted to be actuatedby the roll back 14 to act through the bell-crank 82v and the abutment plate 30 to retract the latch bolt.: I The; latcl1 bolt is adapted to bQ I'GVBI'SGddII: posit-ionin ,the. locln Thehlock is further, provided with two knob vshanks 36.which extend through. apertures in ,opposite sides,

ofthe lock case so as to position them en'd totend they being. held in position in. any

suitable manner.

The parts/above refer red to i inayi be preferably are of a well known construcg.

tion. I In my-improved lock as illustrated inthe drawings, Iprovide a removableanclreversi ble block ,50 and twospecial hubs 38 mounted; on the ends of the knobshanks. 3.6 so as. to} be turned therewith when" free to turn These hubs are arranged side by;side and each of them is provided. with the usual up-f wardly extending tongue 40 that projects between the abutment lug28 and theabut- Inent plate 30 0f the'latch bolt, andis fur ther provided} with a forwardly extending hub lug 42, the lugs 42 being engaged by;

thespiral spring 44 having one end engaging bothlugs and its other end secured to a post 46 on the casing, the same as in the usual two-hub lock. Each of thehubs 88 is, however, further provided with a rearwardly projecting stop lug having its '7 endjfaee ai l ztnged' substantially in thevplene "of the upper faee of the bloekbOyterhOvably -:imdunted in the'llower rear eorne'r of the membieifsi52, theerib' being received: in one f 1y giieate 'fthan, the -Width'oteaeli of the hubs j'll efibloek" may be plztjc ed indiln'ee' diiferentposi'tions' in ithe lo'ckca'se, o'i' it may I be? entirelyremoved "from the "1001? case.
